(CNN) -- A wind-whipped fire in the hills above Santa Barbara, California, expanded to 400 acres late Tuesday, putting 1,200 homes under a mandatory evacuation order and another 1,000 under an evacuation warning, emergency officials said.

The flames are burning within a mile of several homes, said Pat Wheatley with the Santa Barbara County Emergency Operations Center. There have been no injuries, no homes or businesses damaged and only sporadic power outages in the county, she said.

The wildfire began in the Cathedral Peak area around 1:45 p.m. (4:45 p.m. ET), prompting at least seven school closures for Wednesday.
